He didn't charge a lot of people last year, and charged people the unpaid amounts a couple of months ago in a one off charge. And I believe he tried charging people who had also cancelled. Not to mention he was talking shit about his customers on Discord and disclosing their details. There was a big uproar about it on /r/simracing.
Stuffed up their payment systems so people had been getting premium for months and not paying for it. Instead of copping it on the chin they tried to claw money back from people. Did not work out to well.
